我正在尝试将基本的IntentService / BroadcastReceiver组合在一起。 是的,我知道目前的情况并不是很有用,但我只想让广播正常运行。 服务接收我的初始意图,但接收方没有得到返回广播(调试器)。其他答案对我没有帮助,我觉得我已经尝试了一切。它必须是微不足道的,但我不能把它放在它上面。
显示活动:
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val filter = IntentFilter()
filter.addAction(Constants.BROADCAST_ACTION)
filter.addDataScheme("http")
val dsl = DownloadStateReceiver()
LocalBroadcastManager.getInstance(this).registerReceiver(dsl,filter)
buttonLogin.setOnClickListener({
var loginIntent = Intent(this,RawRestJsonPull::class.java)
loginIntent.putExtra("userName",editLogin.text.toString())
loginIntent.putExtra("password",editPassword.text.toString())
this.startService(loginIntent)
})
}
class DownloadStateReceiver : BroadcastReceiver()
{
override fun onReceive(currentContext: Context, incomingIntent: Intent) {
Log.d("?????","d")
}
}
}
服务和动作常数:
class RawRestJsonPull : IntentService("rest" ) {
override fun onHandleIntent(incomingIntent: Intent) {
var outgoingIntent = Intent(Constants.BROADCAST_ACTION)
var status = 0
var userName : String? = incomingIntent.getStringExtra("userName")
var password : String? = incomingIntent.getStringExtra("password")
outgoingIntent.putExtra(Constants.EXTENDED_DATA_STATUS,status).putExtra("userName",userName).
putExtra("password",password)
outgoingIntent.flags = Intent.FLAG_INCLUDE_STOPPED_PACKAGES
LocalBroadcastManager.getInstance(this).sendBroadcast(outgoingIntent)
}
}
class Constants
{
companion object {
val BROADCAST_ACTION = "com.example.hubert1224.xxx.BROADCAST"
val EXTENDED_DATA_STATUS = "com.example.hubert1224.xxx.STATUS"
}
}

试试
首先让你的BroadcastReceiver成为静态或它自己的类,我不确定Android是否可以使用非静态内部类。
其次,我不确定为什么你的接收器意图过滤器有
filter.addDataScheme("http")
但是你错过了你从服务中解雇的意图,如果你不需要它,就把它删除。
